用标准圆弧样板测量零件的圆弧半径,在工厂车间是最常见的方法,它是根据光隙的大小和位置来判断被测圆弧的合格与否。我们测得的光隙 f 值是被测圆弧的线轮廓度误差,而不是被测圆弧的半径偏差。国家标准已明确说,圆弧样板是用来检查零件的轮廓度误差,如图1所示,0.14mm 即为圆 It is the most common method to measure the arc radius of a part with a standard arc template. It is based on the size and position of a light gap to determine whether the tested arc is qualified or not. The measured value of the optical gap f is the contour error of the measured arc, not the radius deviation of the measured arc. National standards have made it clear that the arc model is used to check the parts of the profile error, as shown in Figure 1, 0.14mm is round
